"Effective, but expensive."

Let''s start by saying, as far as a product goes - I believe it to be working very well. I feel good overall, and as someone who hates to eat fish, this has really helped me to get Omega-3 into my diet.
I can''t prove with any metrics, but anecdotally, this has really been effective at reducing my inf*****tion, and my general health. The fishy burps that you get with fish oil, are still present, and not really masked by the aromatic added gubbins, so I find taking this with my evening meal, tends to be easier for having less side effects, even if that means slightly less optimal absorption rates.
Cost wise, I find it quite expensive being one of a few supplements that I take to try and balance out a fairly healthy diet, and given that I am a regular purchaser, would appreciate a subscription option if that were offered by Nature''s Best to balance cost vs reliable consumption.

Thank you for taking the time to leave a review.
While, I am glad to hear of the benefits you have experienced, I am sorry to hear that you have been experiencing these symptoms. This is certainly, not something we would expect. I will contact you directly to discuss this further.
Thank you for your feedback regarding the subscription option, I will certainly pass this on to the relevant department. Warming of surface sea temperatures occurs every few years and during 2023 this had a strong effect on marine life, with adult fish moving away from normal fishing areas. Oil yields were very low, meaning the fish were lean rather than fat, resulting in less DHA and EPA being produced. Lack of supply has led to rising costs and we’ve seen prices rocket as demand outstrips supply.
Although we’ve done all we can to absorb costs, we have had to review our fish oil supplements and make some adjustments to prices.
I would also like to add that it is perfectly suitable to take this supplement with a meal.

"Excellent Quality, And Just Like Anything Else I'Ve Purchased From Nature'S Best"
By David Tallentire

I take 2 capsules per day. Admittedly these Fish Oil capsules are A LOT more expensive than the Cod Liver Oil Capsules I used to buy, but in all honest the EPA and the DHA that I would have been getting from them will have been pretty much worthless. So at least I know that with these Nature's Best Fish Oil capsules, that I will be getting a much higher amount of EPA and DHA and as such will be more likely to give me the desired health benefits. In my opinion it's worth spending more to give you the health benefits, than to pay less and get none of the health benefits.
I would't say I feel any different in myself, but I take these for the heart and bloods benefits, both of which I wouldn't feel any noticeable outward feeling benefits. It will be interesting to see what effect these will have made to the triglycerides in my blood or my cho*****rol in general, when I get my cho*****rol checked in around 6 months time.
